Even in the states, it’s more a distortion caused by the big tech centres. A software engineer in Ohio doesn’t command that kind of salary, but in San Francisco or Seattle that’ll buy you a moderately-senior engineer.
And while academic salaries are generally not great, tenured professors at big universities tend to make a fair bit (plus a lot more vacation time and perks than is normal in the US)
It's also caused by progressive tax rates. People take harder jobs based on net wage, not gross wage, so gross wage has to compensate.

On the other hand, a CEO of a well-known nonprofit might command that kind of salary in Ohio. People often underestimate how much the leaders of nonprofits pay themselves.
